This invention relates to sliding clasp fasteners and more particularlyto such fasteners having separable ends. t

It is the object of this invention to provide improved means whereby theseparable ends may be readily assembled together in correct relativeposition According to the present invention the sep# arable end of oneof the stringers is provided with.

it will now be described with reference to the accompanying drawing inwhich:

Fig. 1 is a front view of the two separable stringers in assembledrelation; Fig. 2 is a side view of one of the stringers showing theslider entered in the box or cage.

Fig. 3 is a rear view showing the two stringers just before beingassembled together, and

Fig. 4 is a plan view of the box or cage'. In the accompanying drawingthe sliding clasp fastener consists of stringers I and 2 having theusual fastener elements '3 and a slider 4. The stringer l has a rigidterminal portion 5 to which is secured a.k box or cage 6 by tongues 5aintegral with the portion 5. The open end of the box has .35 a belledmouth and the -upper part 1 is shaped to receive the lower half of thes1ider` I and provide an easy but fairly close flt for it.

The end of the stringer 2 is provided with a rigid terminal portion 8curved in its length and preferably of square cross section.

One face of the box 6 is formed with a groove or channel 8 adjacent toits mouth and 'adapted to receive a rib I0 on the slider for locatingthe slider in correct position for the assembly of the l two stringers.

When the two stringers are to be assembled together the slider is movedto nest in the box I with the rib I0 entering the groove 9. The ter- 5minal 8 of the Stringer is then inserted through the slider and boxuntil it engages the bottom of the box, the tape passing through theslot II in the side of the box. In this position the stringers are incorrect relative position -for the 10 interengagement of the respectivefastener elements when the slider is operated by the pull tab I2. Whenthe ends of the stringers are to be separated the slider is moved tonest in the box in which position the fastener elements are disl5engaged. l

The terminal portions 5 and 8 may be provided with one or moreinter-engageable fastener elements such as I3, I4 (Figs. 1 and 3) toassist in holding the parts against accidental separation 20 when theslider has been moved to engage the fastener elements 3.

While I have shown a channel 9 as a part of the box sto cooperate withthe rib lo (Figs.

2 and 3) of the slider, any other suitable inter- 25 engaging means maybe provided for the same purpose.

I claim:

A sliding clasp fastener having a` pair of stringers with inter-engagingfasteners carried 30 thereby, a slider for engaging and disengaging thefasteners, a box-like member positioned on one of said stringers,atermlnal member on the other 'stringer engageable with the box-likeportion through said slider and a channel in one face of said box-likemember, a rib on the slider engageable with said channel to position theparts relative to each other prior to engagement of the terminal memberin said box-like member and l a fastener element within the box-.likemember o cooperating with a fastener on the terminal member when saidterminal member is fully engaged in said box-like member.
